Abstract: 1,235,933. Polyurethane copolymers. KAO SOAP CO. Ltd. 15 Oct., 1968 [17 Oct., 1967], No. 48870/68. Headings C3P and C3R. Copolymers are prepared by performing a polyurethane forming reaction (e.g. with a diisocyanate and a polyether or polyester glycol) in the presence of a free radical initiator which contains isocyanate reactive terminal groups and an ethylenically unsaturated monomer. Simultaneous or successive polymerization of the monomer occurs with the urethane forming reaction. In examples the initiator is an azo compound having terminal hydroxyl or carboxyl groups. Suitable monomers are styrene and methyl methacrylate.

Title: Fountain brush
IPC: A46B11/00
Filed: 1977-12-02
Abstract: A fountain-pen brush which is often carried by the user in a skirt pocket has a bristle carrier (1) and a handle (3) containing a reservoir (4) for a liquid or pasty medium, a channel (6) extending from the reservoir through the handle and having an outlet (14) at the side, a slide (7) guided in the channel (6), an actuating device on the end (3a) of the handle which is remote from the bristles, a closure part (10) which hermetically closes the reservoir (4) after the medium has been poured in and a connecting rod (9) which connects the slide (7) and actuating device. In order to prevent medium from flowing out when the brush is being carried, the slide (7) closes the outlet (14) in the position of rest and only opens it when the actuating device is actuated. Slide (7) and closure part (10) are at a distance from one another such that the slide (7) seals the reservoir (4) in a position located on the side of the outlet (14) which is remote from the end with the bristles. The closure part (10) carries a bellows (11) which is elastically deformable, is connected to the closure part (10) and to the inner wall (4a) of the handle (3) such that it constantly forms a hermetic seal, and which seals off the reservoir (4). In the position of rest the slide (7) closes the outlet (14) and on being actuated by pressing the closure part (10) is pushed past the outlet (14), opening it, into the blind end of the channel (6). <IMAGE>

Title: Inhibition of the corrosive action of waters of low mineral content
IPC: C02F5/08
Filed: 1963-12-20
Abstract: The corrosive action of acid waters, containing at most 60 p.p.m. of alkaline earth metal cations, is inhibited by dissolving in these waters an alkali metal pyrophosphate which is at least dibasic in a proportion such that the pH reaches 7-8.  The proportion of pyrosphosphate used may correspond stoichiometrically to only a fraction of the alkaline earth cations in the water, e.g. 10-30 p.p.m. of tetrasodium pyrophosphate added to water containing 20-60 p.p.m. of alkaline earth metal cations and pH 6-6.9.  The invention also relates to compositions for use in the above process comprising a mixture of tetrasodium and/or tetrapotassium pyrophosphate and a dibasic alkali metal pyrophosphate, optionally accompanied by an alkali metal ferrocyanide.  A soft water obtained by this process may comprise 20-60 p.p.m. of alkaline earth metal cations, less than 200 p.p.m. of strong anions, 10-30 p.p.m. of phosphate expressed as Na4P2O7 and possibly up to 10 p.p.m. of an alkali metal ferrocyanide, the pH being 7-8.

Abstract: 1,260,123. Packaging machine; transferring articles between conveyers. WENTCROFT ENGS. Ltd. 6 Nov., 1969 [6 Nov., 1968], No. 52489/68. Headings B8A and B8C. In a packaging machine, packets 13 of potato crisps are fed in series on a conveyer 10 to a loading station where indexing plates 17, carried by endless chains 14, push the packets 13 along a fly-plate 18 to indexing positions 19-22, the fly-plate 18 then being retracted to drop the packets 13 on to a platform 23. The platform 23 is then lowered and a second row of packets is collated on the plate 18 and then dropped on to the first row, this operation being repeated until a pile with six layers of packets 13 is formed. The pile is then discharged on to a container (not shown) or is pushed on to a base 28 by a plunger 26. A second pile of packets is then formed on the platform 23 and pushed on to the base 28 by the plunger 26, the two piles being compacted between the plunger 26 and a second plunger 27. A further plunger 31 is then actuated to push the packets into a container (not shown). The packets 13 are fed to the conveyer 10 by a second conveyer (not shown) which travels more slowly than the conveyer 10. In a second embodiment (Fig. 2, not shown), the fly-plate 18 is replaced by two plates (32, 33) which are drawn apart to allow the packets to drop on to the platform 23. In a third embodiment (Fig. 3, not shown) the conveyer 10 feeds the packets 13 one at a time to a slotted plate (35) having pivotally mounted rods (34) in the slots. The rods (34) are then pivoted upwardly to lift the packet 13 into engagement with an indexing plate 17 which is slotted to accommodate the rods (34). An air nozzle (39) also aids in moving the packet from the plate (35).

Abstract: 1360154 Knitting-machines APPALACHIAN ELECTRONIC INSTRUMENTS Inc 20 Nov 1972 [19 April 1972] 53471/72 Heading DIC [Also in Division G4]  Apparatus for monitoring the lengths of yarn supplied from the beams of a warp machine comprises means for marking the yarns, and course counters started and stopped by spaced detectors. The yarns may be marked by electrically conductive or magnetic solutions, and detected appropriately. Alternatively a visible  or fluorescent mark may be detected photoelectrically. In the preferred embodiment three yarns 15A-C pass to a marking device 17 via guides 13. All three yarns are marked by pressing against a pad soaked in a conducting liquid. When the yarns pass detectors 10A-C the course counters begin to run. A fourth course counter is started and set to run for one minute, second detectors 12A-C, which will stop the counters, are spaced along a scale 11, at distances corresponding to the amount of yarn expected to be used during one rack. Revolutions of the main shaft are detected by a magnetic reed switch. The counter readings indicate the number of courses in a rack, if the yarns are running correctly. The detectors comprise cross arms 10W, 10W' set close together so that passage of a yarn completes a circuit between them. Start detectors are connected via amplifiers to one input of multivibrators (FF1-3, Figs. 1A, B not shown). Stop detectors are similarly connected to the other inputs. The outputs, which go high once start detectors have been activated are connected via AND gates to multivibrators (SS1-3). Course counting pulses also supplied to the AND gate will pass via the multivibrators to the counters (CB1-3). Once the counts are completed, detectors 10A-C are deactivated to prevent further, false, counting. They are reactivated at the start of a new count.
